Re: LA-J091P Chip Identification Please
Thank you for your quick reply.
Do you mind me asking how did you manage to find this?
Also, do you happen to know if this chip will fit even though the original chip has pins on the outside?
I am new to this game. So sorry if the question sounds silly to you.Comment

Re: LA-J091P Chip Identification Please
hi.
1) Experience. He and others have built up a database of IC markings from Richtek and other semiconductor suppliers. You can search for it on this user forum. You can also check his logiwiki website for other tidbits of knowledge.Do you mind me asking how did you manage to find this?
2) it is the same part and you can review the full details from the datasheet that can be downloaded here:

Source and replace your defective part. Just be sure to locate the pin # 1 of the original and match it with the replacement.
3) See attached for the laser markings on this component.Attached FilesComment

The equivalent for RT8061A is EM5845, replaced with GDI4A LA-K032P Rev:1.0 (A00), and it is working like a charmComment

Common SPI bios chip programming Questions and Answers
----------------------------------------------------------
Q: I have a bios request,i can`t post my backup as i can`t read from the chip.
A: If you can`t read from it how do you expect to write to it ?.
Q: Why is my bios chip unreadable ?.
A: The programmer is faulty or has a worn or broken zif socket.
The USB cable is frayed,connector pins worn or some other physical damage.
Not enough amperage or voltage to power the programmer properly.

Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)
He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8... -
Hello, anyone here have updated ezp2023+ chip database in .dat file format.
I need to add w25q256jveq chip but I do not know what data should I type.
I'm using the ezp chip dabase editor posted from here https://www.badcaps.net/forum/troubl...ro-programmers

This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
I have an SSD from a 2012 to early 2013 Macbook pro, the SanDisk model SD5SL2-512G-120SE
Attached is a photo of the burnt chip. I'm assuming it's some sort of voltage regulation chip. The numbers are obscured by the damage.
I am attempting to recover data from this SSD, obviously this chip needs to be replaced before anything can be done.
Is there anything else I should check to verify the health of the NAND?
Thanks if anybody knows what part I'm looking for....
